SIGHT FOR SMALL FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 289,081, dated November 27, 1883.

Application filed December 23, 1882. (No lnodel.) Patented in England May 11, 1882, No. 2,215; inFrance June 15, 1882,No.149,581; in Germany June 1S, 1882, No. 20,4113, and in Italy June 30, 1582, XVI, 11,366, XXVIII, 80T.

To all whom it mf/,fy/ concer/2,.-

Be it known that I, Ttroims GILBERT, a subject of the Queen of Great Britain, residing at Loudon, England, have invented new and useful Improvements in Sights for Small Fire-Arms, (for which I have obtained a patent in Great Britain, No. 2,215, bearing date the 11th May, 1882, and sealed the 11th August, 1882,) of which the following is a speciiication.

This invention relates to further improvements in the improved sight for nre-arms for which Letters Patent were granted to me, No. 267,418, dated the 11th day of November, 1&82.

The improved sight described in the specification of my said former Letters Patent was specially suitable for use with Shotguns; and the present improvements have reference to a slight modilication in the construction of the sight, as therein described, and also to certain modifications whereby the sight is rendered specially applicable for ball iire-arms, and also for revolvers.

In order to enable my invention to be better understood, I will proceed to describe the same by reference to the accompanying drawings, in which- Figure 1 is a plan, and Figs. 2 and 3 side elevations, oi' a sight constructed according to my present improvements, showing the construction of sight I have found most advantageous for Shotguns, Figs, 4, 5, and 6, similar views of the form of sight I have found most advantageous for use with rifles or other ball fire-arms, and Fig. 7 shows a plan of a sight suitable for revolvers. The several iigures are drawn about full size.

The sight shown in Figs. l, 2, and 3 is constructed substantially the same as that shown in the specilication of my said former Letters Patent, except that it is formed with only three notches, c, which is the number I have found to answer best in practice, the notch nearest the breech being now cut with small saw-like teeth. In these views, also, only one piece of platinum, d, is shown ixed on the end ofthe center notch, as I have found in practice that one of such pieces is generally sufficient. This piece or center d may be made of either platinum, silver, ivory, or enamel, and thc notch on which the center is placed is rounded, as shown, so that the said center will be entirely out of the sight of thc left eye.

The sight shown in Figs. 4, 5, and 6 is constructed substantially in the same manner as that hereinbefore described, and shown in Figs. 1, 2, and 3, except that it is of apyramidal form, the right-hand side thereof being cut with saw-like teeth or notches, with a groove or recess, e, in the middle thereof, at the end of which is placed the piece of platinuin d. Although this sight is bcstsuited for rides and other ball-arms, it may also be used for Shotguns, and in either case with or without platinum.

For revolvers the sight may be made reversible, as shown in plan at Fig. 7, by forming the fore part of the right side with notches in the reverse direction, and in addition to the notches on the breech end, the sight would be :fixed on a central pivot (or a groove) at f, so that it could be turned to suit either the right or left eye, according to whether therevolver be held in the right or left hand, as will be understood without further description. My improved sights may also be made of ivory, in which case I stain the sides of the notches black, leaving the ends opposite the sight-eye white, or partly white and partly black. The use or" the saw-like teeth isto prevent a glancing-surface on the notched angle, which is presented to the vision of the right eye, and which gives the sight a solid attracting substance to the right eye only. The glancing angle or side of the sight produces a practically-invisible effect to the vision of the left eye only. Under cover of this novel principle the notched part is hidden from the left eye and at the same time exposed to the right eye.

@Lm-win ritmi` Having thus described my invention and ers, having the series of notches at each end, 1o the manner of performing the same, what I and with a central pivot or groove, as and for claim isthe purposes set forth.
